Is it normal to have cramping since I found out I’m pregnant?

I’m 8 weeks now and my first pregnancy symptom was cramping like I thought my period was coming and I still have cramping on and off but it do tend to make me nervous. I’ve never had any bleeding but I’m constantly worried I’m going to miscarry even though this is something I’ve had since I’ve found out. I’ve also been worried about a ectopic pregnancy and they’ve never been extreme but sometimes I feel more cramping on my right side where I ovulated from (I get ovulation pain) and I do have some discomfort, and being constipated don’t help
